Leider entspricht das SRXL Protokoll des SPEKTRUM AR9020 Empfängers nicht vollständig dem SRXL Standard. Wir bieten daher eine speziell für diesen Empfänger angepasste MICROBEAST PLUS Firmware an, die das Signal dekodieren kann. Diese Firmware kann über die [[StudioX_UpdateInstructions/en|Updatefunktion von StudioX bezogen werden]]. Sie hat dieselbe Versionsnummer wie die Standard Firmware, trägt aber den Zusatz "modified SRXL for SPEKTRUM AR9020".<br /> | |||
<br /> | <br /> | ||
''' | '''Bitte beachten:''' Diese Firmware kann nicht mit Multiplex Empfängern mit SRXL V2 Signal verwendet werden. Ausserdem funktioniert sie auch nicht mit SPEKTRUM Empfänger mit korrektem SRXL Protokoll, wie z.B. dem SPEKTRUM AR7700 und es kann kein anderer Empfängertyp als SRXL ausgewählt werden. [[Manuals:MB_Plus:Receiver_setup_menu_A/de|Einstellpunkt '''A''']] im Empfänger Einstellmenü wird automatisch übersprungen! In Hinblick auf die restliche Funktionalität besteht ansonsten keinerlei Unterschied zu der "normalen" MICROBEAST PLUS Firmware. Ein Wechsel zwischen den verschiedenen Firmware Versionen jederzeit möglich, ohne dass Einstellungen neu vorgenommen werden müssen.<br /> | ||

The rotation speed of the helicopter is only determined by the length of the stick output signal. The gyros measure the actual rotation rate and the system will move the servos until the helicopter reaches the rate that is commanded by the stick position. So simply increasing/decreasing the stick throw (mostly done by increasing/decreasing servo throw or using DualRate in the TX for the specified function) will increase/decrease rotation rate.<br /> | |||
The presets at Parameter menu point '''B''' are nothing else than different preset DualRate/expo curves inside MICROBEAST / MICROBEAST PLUS making the heli rotate slower or faster at a given stick input and making the stick contol more or less sensitive around stick center position. Choose the preset that fits your preferences best and that gives you a good amount of rotation rate. Using the presets (except for the "Transmitter" preset) it is recommended to not change the output signal in the TX significantly as especially when using expo this will bend, compress or stretch the internal curves, leading to very strange flight behavior (anyhow, doing small adjustments in stick throw, i.e. for slightly increasing the roll rate should work without any issues).<br /> | |||
<br /> | |||
If you want to create your own control style easiest thing to do would be to switch Parameter menu point '''B''' to preset blue (="Transmitter") and adjust the curves in your transmitter just as you like. Therefor we suggest to start with a setting of 70% D/R and 25% expo on cyclic and 85% D/R and 40% expo on tail in the transmitter and adjust the curves accordingly. When setting parameter B to "blue = TX" the internal curves in MICROBEAST will be "disabled". Here 100% stick input will give a rotation rate of apprx. 600deg/s on the rudder axis and apprx. 300 deg/s for the cyclic movements (this may vary depending on TX brand as any manufacturer use another signal output as maximum, so this also can be 107, 110% or 95%).<br /> | |||
<br /> | |||
We are often asked which percentages of expo or dual rate corresponds to the different presets. As manufacturers calculate expo curves different, we can't tell you what our preset curves correspond to which TXs expo values as we use our own expo calculation and there is no data available for comparing. We did out fly these values and programmed them in the source code so we can't tell what these are in Futaba or JR percentages. If you want to use a specific preset as your starting point we suggest to connect your MICROBEAST to the StudioX software. Here you can see the different values for each control behavior preset and you can save a custom preset for which you may use the given values and adjust them with StudioX until they perfectly fit your flying style.<br /> | |||

{{QUOTE|'''' | {{QUOTE|* Note that the rotation rate in first line has nothing to do with your cyclic pitch adjustments at Setup menu points J or L and also has nothing to do with the cyclic pitch when steering cyclic on the ground! Especially when controlling slow rates do not get confused when the system will move the servos to full cyclic deflection. This is normal behavior of the system as the heli when the heli is standing on the ground and can't move. In flight the system will automatically control the pitch as high as necessary to maintain the given rate. So always setup the cyclic pitch as mentioned in the manual and do not rely on what you see when moving the sticks on the ground!<br /> | ||
<br /> | |||
* If the heli does not flip / roll / rotate fast enough even if you've fully increased the stick throw in the transmitter check the maximum amount of cylic pitch at Setup menu point L and the maximum rudder servo deflection at Setup menu point '''E'''. When the cyclic pitch or tail pitch is not sufficient of course the system can't rotate the heli faster than the pitch allows.}}<br /> | |||

Dieses Verhalten ist vollkommen normal, da das System nicht einfach nur vollen Nick-, Roll- oder Pitchausschlag steuert. Abhängig von der momentanen Lage und Drehgeschwindigkeit des Helis steuert das System ganz gezielt mehr oder weniger stark. Dabei kann es beim Test auf der Werkbank zu Servozucken oder abruptem Wechsel zwischen verschiedenen Servopositionen kommen, da eine Bewegung des Helis von Hand nicht der tatsächlichen Bewegung im Flug entspricht. | Dieses Verhalten ist vollkommen normal, da das System nicht einfach nur vollen Nick-, Roll- oder Pitchausschlag steuert.

=== | ===AttitudeControl does not level my helicopter perfectly=== | ||
'' | ''On the ground everything seems perfect and even the first time I switch on AttitudeControl in flight on the helis levels OK. But after some time the heli is (extremely) tilted to the side when I switch on AttitudeControl again.''<br /> | ||

The MICROBEAST PLUS AttitudeControl uses gyro sensors and accelerometers to build up the artificial horizon which is necessary to determine the heli's absolute position in space. This artificial horizon is highly dependent on the sensor data input and if the sensors fail, also the artificial horizon will. The sensors can especially be influenced by vibrations which cause them to show wrong data or loose some data at all. This will cause wrong calculations and in consequence cause a wrong repositioning of the heli. The gyro sensors of MICROBEAST PLUS typically are very vibration resistant and you might not see the influence of vibrations in normal flight without AttitudeControl. But as the calculation of the artificial horizon mainly is a big sum of all the sensor inputs over time, even the smallest influence can cause an offset of the system. Additionally the accelerometers are much more sensitive to vibrations than the gyro sensors. As these are not used in normal flight most of the time, you will not see a direct influence of vibrations on them. But for the AttitudeControl these sensors have an important role and the system can only work with limited capability if these sensors fail.<br /> | |||

* | * Make sure the system is perfectly aligned to the helicopter's rotation axis. Otherwise the measurements will be incorrect by principle. | ||
* Make sure the system is not touching the helicopter's canopy and loose wires can't hit the device in flight. | |||
* Please make sure your helicopter is running smooth and absolutely free of vibrations. Particularly with very small electric helis this is sometimes a difficult task, as there is not much mass to compensate for the vibrations and all electric components are placed very close to each other. If you see or hear any abnormalities like twitching tail or loud, vibrant noise it is very likely the AttitudeControl will not work as expected. You may try to place the MICROBEAST PLUS unit at a different location on the heli or mount it with a different sort of gyro pad to compensate for those vibrations. Anyhow the best solution is to find the source of vibration, i.e. by removing tail and main blades and letting the motor run on the ground, and change defective/unbalanced parts. | |||
* High temperature changes can cause the sensors to drift and in consequence cause the artificial horizon get offset. When it's very cold outside or very hot make sure the system can acclimatize when moving the helicopter from warm to cold or from cold to warm.<br /> | |||
